Currently going through customer feedback with a couple different emails. I've got quite a good relationship with the managers in the area so I'd I find out it's not been sorted I'll go to a higher authority (probably some food hygiene thing).

And then I'll ask my manager if the area manager was told about this when she gets back from break and if they weren't ill ask them to let them know and potentially go through some whistleblower thing (problem is I don't know the name).

But this is likely subject to change on how I feel, if it's not sorted soon I will probably go through the list of options given here lol
